Each folder contains maps of each pTRM acquisition step. pTRMs were applied with a 200 microtesla field oriented in the north [D,I = (0,0)] direction.

Source maps are upward continued before fitting. Although different sources are upward continued by different amounts, all demagnetization steps for the same source are upward continued by the same distance. 

Upward continuation distance (microns):
9a: 100
9b: 75
9f: 50

These amounts are identical to the upward continuation distances for thermal demagnetization of NRM.
